` o A Letters Patent No. 107,765, dated September A27, 1870.

* .IMPnovEMi-:Nr IN sPLlN'r-PLANEs.

`The Scheduie referred `to in these Letters'Patent ,and making part of the same Be it known that we, PHILANDER N. Duarte and DAvrD I)nUMMoND,of McGregor, inthe county of Olaytonandin theState of Iowa, have invented certain` new and usefulImprovements in- Splint-lane. orSlat-Cutter;v and doo-hereby. declare that `the f ollowing is a full, clear,"and exact description vthereof,

reference being `had, trofthe accompanying drawing nce marked thereon, making a part ofi-this specification.

Our invention relatesto that kind ot' planes used itcuttlng thin-strips or rsi-ats,v for rustic shades, andl other purposes, andconsistsu First, in placing thecutter undelthe bottom the Plane, level with the edge of lthe board from wliiclrtlie `strips or slats `are to be cut; i l

Secondfin the construction otthe mechanism for` holding the cutter in 4its place; and 1 l Tbirdyin the construction ofthe mechanism for regulating the thickness of the` strips. or slats to be which our invention appart-eins to make and u se the` same, we will nowproceed lto describe its Vconstruetion and operation, referringt the `annexed drawing, in which plane, o y

Figure 2 is a transverse .vertical section; and o Figure 3, abottom view of tbe-same.

l Figui-e4 shows the end of the cuttenwith the `channel-plates in the plane.

handle, B;

A represents the body of our plane ln'ovidedwith a lAlong one side of the b ody is secured a bar, C,

` projecting `below the plane asuitablc distance to forni a guard'or` guide for the tool." l

Betweeny the under side of the plane A and the bar G is formed a groove, in `which theinner edge of thev cutter l) is inserted, said cutterlbeing. lnidlevel under ,fthe lower side, or against' the lower side of th'e plane A.

` "lhe cutting-toolI) is held by means .of a stirrup,

UE, constructed as shown in ig.f2, and passed up through the plane A, with ascrew-shank at .its upper o end, which projects aboretheplane Ontbs screw-shankis placed a thumb-nut, G, by means of which the stirrup is raised so as to firmly bind thecutting-tool.- The ptchof the cutting-edge of said tool `is regulated by means of two inclined .screws, `I' I, passing through. the plane A and bearing against the upper surface of the cutter, one on each side in front of the stirrnp E.

The tool-bit being'on a level with the edge of' the board, it splits with less liability to break the fiber on theback of the slat. When it iste be taken out to sharpen, it can be putvback'to its place accurately and cut all the work ot' uniform thickness.

lhe two screws, I I, forcing the cutting-edge ofthe cutter to the desired position for uniform thickness, may, of course, remain in thesameposition for `any length of time without change, even though the cutter is taken out and replaced again. 1

In the channel on the under side of the plane A, between it and the cutter l), are placed three channel-plates,. a, b, and cl, the relative positions of which lare' plainly `indieatedin fig. 4. Theobject of these' plates is to further enable us to vary the thickness, it we desire to do so. Y i

The back or upper side of these platesmay be provided with inclines'to enable them to be pushed forward or back.

The middle plate (lis made so that it can readily be taken out and another of dierent size substituted.

Having thus-fully described our invention, What we claim as new, and desire to secureby Letters Patent, isrIhe combination, with the stock A, of the lat-laid Vtool D, channel-plates a b d, stirrup E, nut G, and screws I I, all constructed to operate substantially as setforth.

I n testimony that we claim the foregoing, we have` hereunto set our hand and seals this 26th day ofMarch 1870. PHILANDER N. DRAKE. [1.. s.] DAVID DRUMMOND. [Ik s.]
